Prince George has reportedly been given an adorable nickname by some of his friends from school.

One parent told Vanity Fair that Prince George is known as “PG” in school, an abbreviation of his moniker. However, this nickname may not have originated from the young students at St. Thomas’s Battersea.

James Bickerton, a journalist for Express, claimed that Kate Middleton and Prince William also refer to Prince George as Tips, which is an apparent reference to the PG Tips tea brand.

Meanwhile, Prince George is not the only member of the royal family who has a unique nickname. In fact, the third in line to the throne also has unique nicknames for the other members of the royal family.

For instance, Prince George refers to Queen Elizabeth II as Gan Gan. Two years ago, Middleton shared an insight into the monarch’s relationship with Prince George and said that they are quite close.

“He calls her Gan Gan… She always leaves a little gift or something in their room when we go and stay, and that just shows her love for the family,” Middleton gushed.

Earlier this year, a royal fan also crossed paths with Prince George and Princess Charlotte during their walkabout with their nanny. When the source approached the young boy to ask what his name was, Prince George referred to himself as Archie.

It is unclear if Prince George was asked to say the fake name when he’s out in public to hide his identity.

“Just to be friendly I engaged in a bit of small talk and I asked George what his name was, even though obviously I knew it. To my astonishment, he said, ‘I’m called Archie’ with a big smile on his face… I don’t know why he calls himself Archie but kids often play with their names and I think it’s lovely,” the source told The Sun.
